CAGE-RINGFOR BALL-BEARINGS.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed ly 17,1906. Serial No. 326,631. I

Tea/ll whom it may cgnecrn:

- Be it known that I, JOHANN MICHAEL MODEL, merchant, a subject of the King of Bavaria, residing at No. 11 Seestrasse,

Schweinfurt-on-the-Main, (German Empire,)

'- spheres are kept at equidistances apart in through the balls merely sliding along, owing their-race, whereby all directiriction of the balls against each "'otherdiirin is prevented, while by means of fillers of felt or the like the lubricant is held and distributed. Furthermore, all useless play and concussion of the balls when running are obviated and perfectly'silent working insured. In addition to these-main features the new cage has the advantage of being considerably easier and cheaperto manufacture than prior types of'cages. Itmay consist merely of a metal band, which may be formed, for instance, by bending a strip of steel, there being thus no waste of material through'stamping or the like; The balls being embraced by the undulating band, all possibility of their being fracturedby collision; owing to shocks is obviated and damage to the bearing thus effectively prevented, nor canthe race be injured to one ball acting as a brake on the other.

The serpentine form of'the cage and .the presence of the felt or like-fillers also prevent the cage itself from getting in'ured, and in this manner also flying out o the balls at high speeds, such as sometimes occurs when separate spring spacing devices are used, is

rendered impossible.- The soft fillers like.- wise prevent the access of foreign particles to the race and insure regular distribution of lubricant.

My invention is illustrated in the accompanying drawings, in which Figurel is an elevation of a cage-ring with balls. Fig. 2 shows a side view of a portion ofthe cage-ring with balls as it would appear when straightened out. Fig. 3 is an elevation and part section of a ball-race fitted with the cage-ring shown in Figs. 1 and 2-. Fig. 4 shows the other side of Fig. 3. Fig.

5 is a plan of a cage-ring with balls for a step or sup orting bearing. Fig. 6 shows a side view 0 straightened out.

I The cageof the strip recesses to receive the and a portion of this cage-ring with balls as the drawing shows,' consists of a strip of steel or other material a which is given a sinuous shape, sothat a ball b can be pressed into each undulation or bend 0. These undulations at those parts with l which the balls contact in the direction'of running are provided with recesses or inden tations d, in which the balls hang after insertion in the cage, as shown in Figs. 1 and 2.

.In the bends f between each two balls there are inserted, as'shown in 3, fillers e,-of,- felt, or other soft material, ]which takes up the lubricant. These fillers receive a hold from the salient back walls of the re cessesd. The cage-ring shown in Figs. 5 and 6 is designed to step or supporting bearings and differs from that just described only in so far] that the undulations c of the stripe, which receive the balls I), lie radially. instead of parallel to the center axis of the ball race, as in the construction illustrated in Figs. 1 1304:. The walls of the undulations are provided, as before, with recesses d at the parts with which the balls contact, whereby the balls {So are firmly held. The back of the recesses at the same time constitute swells between; whichthe lubricating-fillers e are inserted."

. Havingtfius described my invention, what;

I claim as new, and desire to secure byLetters Patent, is-

1. A cage-ring, comprising a sinuous metallic strip, the walls of the undulations-of which'are indented so as to form on one side.

on the other side swells; and fillers ofsofti' 1 material inserted in the undulations between the swells; substantially as described. g

2. A ball-bearing, comprising in combination two concentric collars grooved to pre sent a race; a'sinuous cage-ring located in the race and having substantially parallel portions, the alternateundulations 0 which ring have indentedwalls; balls' locatedin these undulations and soft fillers located 1n.

ice

the other undulations; substantially as-de-"' scribed. I

In witness whereof 'I have hereunto signed my name, this 30th day of June, 1996, in the-- presence of two subscribing witnesses JOHANN MIOITAEL MODEL. Witnesses; C. B. DE SAONE,
